The NYS Regents Chemistry Exam Is Three Hours of Stoichiometry You Can't Afford to Guess Your Way Through
The Regents Chemistry exam is standardized, predictable in structure, and brutally unforgiving of carelessness. Most students who fail it don't fail because chemistry is hard. They fail because they never practiced with actual past exams under timed conditions, and they don't understand how the Scoring Criteria document works—which is worth 30% of your total grade on its own. The term High Marks Regents Chemistry Made Easy generally refers to a study guide and problem set published by High Marks Education that aligns directly with the NY State curriculum framework. It's not a magic bullet. It's a practice resource. The real value comes from how you use it alongside the official Scoring Rubrics, which most students completely ignore until the week before the test. The book covers the eight major content areas: Set I (7-12 questions), Set II (11-17 questions), Set IIIa (11-15 questions), and Set IIIb (8-12 questions). Each section maps to specific competencies on theNY P-12 Science Learning Standards. The questions follow a trajectory from basic recall to multi-step calculations and data analysis. Knowing this progression matters more than any single chapter review.
How to Use This Material Without Wasting Three Weeks
Start with a diagnostic. Take one past Regents exam from 2019 or later under strict timed conditions—3 hours, no notes, no phone. Grade it using the official Scoring Criteria, not an answer key. This takes approximately 45 minutes if you're methodical. The score you get tells you exactly where you are. Most students score between 55 and 72 on their first attempt. That's not a disaster. It's a baseline. From there, work through the High Marks guide section by section, but only after you've identified your weak areas from the diagnostic. Don't read it cover to cover. That wastes time on material you already know. Focus your effort on the topics where you lost points. The most common failure points I see are:
- Stoichiometry with limiting reactants (Set IIIb)
- Equilibrium and Le Chatelier's Principle interpretation
- Thermochemistry Hess's Law calculations
- Nuclear chemistry half-life problems
- Polar vs nonpolar molecular geometry reasoning
After each chapter in the guide, go back to the corresponding past exam sections and do those questions again. This reinforces the specific question formats the Regents uses. The exam recycles concepts constantly. You'll see mole-ratio problems appear in Set I one year and in Set IIIb the next. Here's something that catches students off guard. The New York State Education Department publishes a separate Scoring Criteria document for every single Regents Chemistry exam. These documents don't just tell you the right answers—they show you exactly how partial credit is awarded. For Set IIIb open-ended questions, you can often earn 1 or 2 credits out of a possible 2 by showing correct setup even if your final calculation is wrong. Students who ignore this lose points they shouldn't lose. I worked with a student last spring who was consistently scoring around 65. He understood the chemistry. His problem was that he wrote complete prose sentences for Set IIIb answers when the rubric accepted concise, equation-based responses. Once we switched his answering strategy to match the rubric's expectations, his score jumped to 81 on the same exam format. The content didn't change. The delivery did.

What This Resource Doesn't Do Well
High Marks is strong on practice problems and weaker on conceptual explanation. If you've never seen a topic before—say, formal charge calculations or titration curve interpretation—the book's brief review sections won't be enough. You'll need supplemental video lectures or a teacher's clarification. The guide assumes you've already had classroom instruction and need rehearsal, not introduction. The answer explanations are also abbreviated. Some solutions skip steps, particularly in multi-step stoichiometry. This is fine if you can follow the logic. It's frustrating if you can't. When I hit one of these cases, I'd go to the College Board's AP Chemistry resources or openstax.org for a more thorough walkthrough of that specific concept, then return to the problem.
The Timed Practice Schedule That Actually Works
If you're starting 8 weeks before the exam, here's a realistic breakdown: Weeks 1-2: Diagnostic exam + review of foundational math skills (scientific notation, significant figures, algebra rearrangement). These three things account for roughly 15% of lost points on every exam I've graded. Students skip this step and pay for it later. Weeks 3-5: Targeted practice through the High Marks guide, rotating between sets. Each session should include at least one full Set IIIb response written under timed conditions and graded against the official rubric. This is where you build the answer-writing muscle memory.
Weeks 6-7: Full past exams under real conditions. Alternate days between Set I/II/IIIa practice and full 3-hour exams. Grade everything. Track which question types consistently cost you points. Week 8: Light review. Focus on your persistent weak areas. Sleep matters more than cramming at this stage. The exam tests recognition under time pressure, not new learning.
Where to Get the Guide
The High Marks Regents Chemistry Made Easy guide is available through major retailers and directly from the publisher. It's updated periodically to align with curriculum changes, so check the edition date. The 2022 and later editions reflect the current exam structure. Older editions may still be useful for practice but won't match the exact question distribution on recent exams. The New York State Education Department website also hosts every past Regents Chemistry exam from 2011 onward, along with the corresponding Scoring Criteria. Those are free and essential. Use them alongside the High Marks book, not instead of it. The combination covers both practice volume and official answer expectations. The exam is passable if you treat it as a skill to rehearse rather than a test of innate talent. The gap between a 65 and an 85 is almost entirely practice quality, not intelligence. Work the past exams. Read the rubrics. Fix the specific mistakes instead of repeating the same ones.
